I will only drive the car once and a while, maybe 1,000 miles a year. Not worried about being a street motor, I usually stay on the local roads at 50 to 60 MPH. So I was thinking 11:1 or as high as I could go with ported big valve heads and a decent solid cam. Going with a T400 trans with I don't know maybe 2000 stall???(or I have some powerglides i could use) and 4:11 gears. I am curious on the heads I see 195 cc runners up to 215 or so, is that the amount of porting in the runner? how big of a head can be run on this set up? I was comparing my expectations to the stock 327 that made 365 HP or whatever the HP was on that motor, or was that motor already pushed to the limit? Seems I could built it a little better than that one and at least get to 400HP?
